室内分布系统多系统合路干扰影响分析

铁塔公司成立后，室内分布系统的建设由铁塔公司负责，未来多运营商共建共享将成为室内分布系统建设的主要方式，这就为多系统接入平台（POI）的应用提供更为广泛的舞台。POI的引入节省了重复投资，但由此带来的多系统干扰问题逐渐成为各运营商关注的重点。本文基于不同的POI类型，针对可能的干扰问题开展了理论分析及测试，为POI引入后的潜在干扰问题给出了解决方案，为室内分布系统的建设提供指导。

Interference Analysis of Co-channel systems for Interference Analysis of Co-channel systems for

After the establishment of the tower company, the construction of the indoor distribution system is the responsibility of the tower company, so the sharing of the multi operators will become the main form of the indoor distribution system. Which provides a broader stage for the application of the point of interface (POI). The introduction of POI saves the duplication of investment, but the resulting multi-system interference gradually becomes the focus of the operators. In this paper, based on the different types of POI, we carry out theoretical analysis and testing for the possible interference, give a solution for the potential interference problems of POI and provide the guidance for the construction of indoor distribution systems.
